Abstract: A multicolor printing device has a plurality of successive print heads (13a-13d) along a path to print images from a dye web (40) of a respectively different color at each head on a dye receiving sheet (20) successively advanced to each head in a set of printing cycles corresponding to the number of heads. The device is operated under end of web roll responsive control to prevent any web (40) from reaching an end of roll condition during a set of printing cycles. Each web (40) has a predetermined number of successive dye areas (51) and intervening dye-free areas (52) that are sensed and counted, as the web (40) moves in increments in the successive cycles, to control the operation and to register the successive dye areas (51) with the associated head. When the count indicates that the number of dye areas (51) not yet subjected to a printing cycle on the web at any head (13) corresponds to the number of heads preceding that head (13) along the path, the device is controlled to prevent further cycle operation at the first head (13) while permitting respective completion of the cycle operations for already advanced sheets (20) at the remaining heads.

IPC: G06K7/10

Abstract: The camera system (10,100) of the present invention simultaneously searches for a number of differing optical acquisition targets (44). Upon detecting an acquisition target (44) it decodes according to corresponding differing decoding algorithms. To facilitate this operation there is a system bus (170) as well as a dedicated data bus (172) for applying a scan signal of an optical scanning device (154) to differing detection circuitry. This system may decode, for example, both bar codes and concentric rings. The scan signal is constantly adjusted according to both a dark reference for correcting offset and a white reference for correcting gain. The gain is also corrected according to the scanning rate as well as the amount of illumination present. A measure of this illumination may be applied directly to the optical scanning device (154) by way of a fiber optic cable (402) which transmits light from the illumination source (15). When detecting concentric rings the system of the present invention uses stored templates which represent a number of transformations of the target (44), for example, a number of magnifications. When the transformation of a target (44) is determined, the corresponding stored template is correlated with the scan signal from the optical scanning device (154). To detect concentric rings the scan signal is applied to interleaving circuitry (180) which correlates more than one scan at a time to provide constant throughput even though the stages of the detector operate at different speeds. Optical calibration is eliminated by fixed optics wherein all optical elements are rigidly mounted at very close tolerances. The illumination source (15) is disposed on one focus (22) of an ellipse (18) wherein the other focus (24) is disposed at the maximum scanning distance and the reflector (14) is formed to define the illumination ellipse (18) to maximize the light applied to the object (42). The various heat producing elements are disposed in sealed compartments (40a,b,c) which are cooled by forced air which is circulated through a heat exchanger. A real time focusing system is provided wherein the distance from the scanning device to an opposing surface is constantly monitored and the system is constantly focused according to the distance.

Abstract: When bit streams consisting of a number of information words are switched through in the switching networks of digital communication systems, bit corruption occurs in the form of wrong through-connections. To discover and to eliminate these wrong through-connections, checks are introduced in the form of synchronous monitoring. Thus, it can be determined by means of selective channel-by-channel checking of the respective information words whether the error is also present over a relatively long period. If this is so, the corresponding connection can be interrupted and error correction measures can be initiated. <IMAGE>

Abstract: A radiation detecting element is disclosed, particularly a photographic element having a radiation detecting composition, in particular a silver halide emulsion. The composition provides the element with a wavelength of peak sensitivity,  λpeaksens , and a decreasing sensitivity around  λpeaksens . An absorber dye of defined characteristics is chosen, which has the effect of decreasing the change in sensitivity which the element otherwise has without the absorber dye (that is, the absorber dye increases the wavelength range over which the sensitivity is relatively constant). The element is preferably sensitive to infra-red.

Abstract: An electron device of the present invention comprises an i-type diamond layer formed on a substrate, and an n-type diamond layer formed on the i-type diamond layer and having a first surface region formed flatly and a second surface region containing an emitter portion, which are set in a vacuum container, in which the emitter portion formed of the n-type diamond has a bottom area 10 or less µm square and projects relative to the first surface region. In the n-type diamond layer, a difference is fine between the conduction band and the vacuum level. Also, since the n-type diamond layer is doped with an n-type dopant in a high concentration, metal conduction is dominant as conduction of electrons. Therefore, setting the temperature of the substrate at a predetermined temperature and generating an electric field near the surface of the emitter portion, electrons are emitted with a high efficiency from the tip portion of the emitter portion into the vacuum. Even though the emitter portion does not have a tip portion formed in a very fine shape, electrons can readily be taken out into the vacuum by the field emission with relatively small field strength. Consequently, the emission current and the current gain increase and the current density in the emitter portion decreases, thus increasing the withstand current or withstand voltage.
